Water Management Plan of Danube-Prut-Black Sea basin in Republic of Moldova included a groundwater component according to Water Framework Directive (WFD). Seven principal aquifers were delineated into eleven groundwater bodies (GWB). Every GWB were characterized for their quantity and quality parameters. The new monitoring sites were proposed for GWBs, which have no monitoring points. The groundwater quality analysis included major ions, heavy metals, modern and obsolete (POPs) pesticides. GC/MS technology was used for the pesticide determination. The used method for the pesticide determination was validated and proposed for the implementation in the national monitoring programs. The obtained results showed an absence of POPs substances in groundwater samples. Several modern pesticides and trifluraline were determined in GWBs for shallow aquifers in springs and shallow wells. The conclusion is that deep GWBs have no a contamination affect from point and diffuse pollution sources. The shallow GWBs affected slightly from diffuse pollution as a result of the agriculture production in the vegetation season. The local shallow groundwater contamination is indicated also near contaminated sites.
